To be honest, I have seen many DEX claiming that they wanted to make Bitshares DEX easy to use with a less-confusing UI/UX but none has lived upto their claims. Go check yourself Cryptobridge, cryptonomix, openledger, rudex and others all are just ditto copies of bitshares dex. I think DEV has done so far a wonderful job with the UI, let's see what other features they include in future.
